An online program featuring jockeys' insights into their rides before race meetings has hit a hurdle after its introduction at Caulfield.

Racing Victoria chief steward Terry Bailey said jockeys could be in breach of the rules if money is being exchanged for their insight.

Ride Guide, the brainchild of jockey Chris Symons, began on Saturday in conjunction with media company Unscriptd with jockeys riding at Caulfield giving their thoughts on their rides via bookmaker Ladbrokes betting site.

Bailey and his team only became aware of the commencement of the service on Friday.

He said they tried to have it taken down but were told the removal could crash the entire Ladbrokes site.

Bailey said he was aware Ride Guide was coming but Racing Victoria and the integrity department had not ticked off on it.

"We are happy with the concept but the one minor problem is how it is distributed," Bailey said.

"If there's money changing hands then they (jockeys) need to get permission from stewards.

"This isn't something pointed at Ladbrokes."

Bailey said he went through 90 per cent of the footage before Saturday's meeting and agreed there was a place for it if managed properly.

As a result of jockey Andrew Mallyon's comments, stewards interviewed Tony Vasil, the trainer of Sir John Monash runner General Truce.

Mallyon revealed General Truce had been freshened at the beach following his last start at Flemington on June 25, spending nine days at his owner's property.

Stewards reminded Vasil he must notify stewards should a horse be removed from his supervision during a preparation.

Bailey said Ride Guide was something the integrity unit should vet before it goes to air.
